A mysteriously speeding object whipping through the solar system has caused some initial concern but has now been identified as the elusive Pons-Gambert Comet (aka C/2012 V4). It has been spotted speeding past Mars on a trajectory that will put it near the sun before it speeds out of site and away from us. This is the first time the comet has been seen since 1827. It should be visible to viewers on December 11th in the Southeastern portion of the U.S. with a brightness magnitude between 9.0 to 9.5 but its trajectory is low to the horizon and may be hard to see. It is measuring 5.4KM in size (3.4 miles) and will pass behind the sun and will not come close to Earth.
